claim-proposal-guardian	Enforce review-gated claim status transitions and epistemic rigor. Prevents direct mutation of SPECULATIVE / COHERENT / CONTESTED / FALSIFIED status.	pre_edit:teaching/ pre_edit:core/cognition/ pre_edit:vault/ manual	true

Before any change involving claim status, TeachingChainProposal, or epistemic_status:

1. Confirm the change goes through the defined review-gated proposal mechanism only.
2. Verify no direct mutation of claim status or epistemic_status outside vault/store.py (INV-29).
3. Ensure user-facing recall respects min_status=COHERENT (INV-24).
4. Block or surface any attempt to bypass review gates.

This skill protects CORE's truth-seeking schema and epistemic integrity.
